Answer:
Length= 22 cm
Step-by-step explanation:
Area = Length x Width
(substitute known values)
374 = L x 17
(divide by 17 on both sides)
22=L
I could be very wrong, but I believe the answer is C
Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
The standard form equation for a circle is
where (h, k) is the center and r is the radius.
The standard form equation for an ellipse is
(center h, k and major and minor axes a and b)
This equation is standard form for neither, but might be general form for one.
